biology quest 1 Flashcards
characteristics of life
organization and cells, reproduction, homeostasis, metabolism, growth and development, change through time, response to stimuli
organization and cells
unicellular or multicellular (cells, tissues, organs, organ systems, organisms)
reproduction
sexual or asexual
homeostasis
maintain stable internal conditions
metabolism
take in and transform energy and materials from env.
growth and development
change in size and form (sometimes metamorphosis)
change through time
evolution via natural selection
response to stimuli
interaction with env. (an organisms reaction or response to chemical or physical change in env.)
diversity
variety of species
unity
genetic code/dna
tree of life
(domains and kingdoms) common ancestor-bacteria, archea and eukaryota (eukaryota- fungi, plantae and animalia) (archea- archea) (bacteria- bacteria)
evolution
characteristics of a pop of animals that changes over time (Descent with modification)
natural selection
organisms that have favorable traits are more likely to survive and reproduce)
adaptation
product of natural selection (favorable traits that are passed down)
three unifying themes in biology
the diversity and unity of life, interdependance of living things and the evolution of life
organs
structures that carry out specialized jobs within an organ system
tissues
group of cells that have similar abilities and allow the organ to function
organelles
tiny structures that carry out functions necessary for the cell to stay alive
magnification
makes object larger
resolution
power to show details clearly
